2. Since you want to move new games to a new HD, you will still need to install them on the "Steam" HD first. After that, go to Steam\\Steamapps\\common\\ and move the entier folder to a new location on a new HD.

3. After the copy is complete, go to the Steam folder and then delete the files in the actual game folder. Leave the folder there, you'll need it in a second.

5. You will then have 2 section in the window, a "Junction Point" and a "Destination." On the "Junction Point" window to the left, you want to find that empty game folder in your Steam folder. Example... C:\\Program Files (x86)\\Steam\\steapapps\\Common\\battlefield 2

6. After you have selected the empty game folder, (You will now see two green check marks on the bottom of the window) Then find the New game folder on the new HD in the window to the right. Select it, and then you can hit "create"

And it's done! This is how I have 1.4tb of Steam games installed on a 300gb HD!

EDIT - Said the Junction Point window was on the right, it's on the left. Sorry about that.
